Andrew P.wrote a review of Julbo Dust Zebra Photochromic Sunglasses on May 2, 2018
Familiarity: I've used it several times
I own other Julbo photochromic products (ski goggles with Snow Tiger lenses) and love the optics and versatility they provide. The Zebra lenses are no different; they adapt so well to different light levels that I almost never have to take the glasses off. The frames and lenses on the Dust have ended up fitting my face perfectly as well, so it's easy to just leave them on. They look pretty "athletic", but I would have no qualms wearing the bright blue frames casually as well. Perhaps the only criticism I have of the lenses is that I find they don't get quite dark enough for sustained really bright usage, for instance on snow in full sun. I've used them for ski touring on a day with variable sun exposure, however, and they performed flawlessly. I think I could use them in really bright light too, but they may not be best for that. I believe they darken into the "lighter side" of Julbo's Spectron 4 category, so for glacier usage or other sustained full sun a dedicated darker lens might be more appropriate. I knew this about them before I bought, however, so it's really not a dealbreaking issue. Finally, they don't work well for me while driving. Julbo recommends against using them for this anyway, and what I've found is that the photochromic attributes don't seem to function as well in the car, meaning they don't darken enough and my eyes feel strained. Outside, however, they seem to function much more effectively. Limitations aside, they're a great general use lens/shade.
